[A11y]: ino-chip accessibilty issues

[Sl1nd]

Bug Report

• Still "clickable" via keyboard for non-clickable option
• Removable icon-button does not provide an aria-label
• Selectable option does not represent a button, although it could be used with clickable option
• Selectable option does provide wrong roles and aria-* properties
• Wrong aria-roles in general
• Trailing-Icon should be included to screenreader focus state

Possible Solution

• Should not be clickable via keyboard if non-clickable option is set
• Remove-Option icon-button should provide accessible name
• The internal html should for all options represent a html-button (especially when clickable could be set in conjuction)
• Selectable option should not render role 'option' with 'aria-selected' states. Selected states should be represented by a html button with 'aria-pressed="false"' aria-pressed="true"https://www.w3.org/WAI/ARIA/apg/patterns/button/examples/button/
• Remove wrong aria-roles (gridcell, row option) and always use button instead
• Include Trailing-icon to screenreader focus
